Although there was a craze on the potential applications of nanotechnology, many of the applications sold are limited to the use of “first generation” passive nanomaterials. This includes iron oxide nanoparticles and zinc oxide in sunscreens and cosmetics.
How iron oxide powder is used in cosmetics
Initially, cosmetics only used nanomaterials in the form of titanium dioxide nanoparticles and oxide zinc. Finding their main use in solar products is one of the reasons why we speak often of nanoparticles in these products because they open the way for other uses known in today's cosmetics.
They are found in the foundations, lipsticks, and eye shadows. Makeup products to "pearly" effect or "light" are based on the optical properties of nanoparticles. In foundations "special smoothing" contains combinations of silicon dioxide nanoparticles and zinc dioxide, which retain the enzyme causing dryness and roughness of skin.
Even toothpastes contain calcium fluoride nanoparticles! There is also nano iron oxide in lipsticks which increases its strength.
Reversible blackening of the pigments used in the foundation, according to wavelength and or intensity of the illuminate is an interesting property. Indeed, thanks to the use of such particles, the foundation is exposed to natural sunlight or artificial light, makeup result is the same. Most of the nanoproducts made of iron oxide have this property.
Currently, no official identification method for nanoparticles has been established, allowing certain undertakings or the cosmetic manufacturers to divert settlement to their advantage by determining the particle diameter at will in order to earn some extra nanometres. You can buy the required quantity online from various iron oxide powder suppliers.
